Peugeot Boxer used as a shuttle by Brazilian Air Force
Mercedes-Benz MB180D
Matra CD, this one used a Rover-based Maxion HSD2.5 turbodiesel, the same one formerly used in the Argentinian-made Ford Ranger. Brazilian company Matra was not affiliated to the French Matra.
This one doesn't need an introduction
Not sure if a Land Rover Defender would qualify as "eco", but it has a 6-speed manual and a turbodiesel under 3-litre. And this one, specifically, is used as an ambulance in my hometown.
Fiat Ducato school shuttle
Emis Art, a Volkswagen-powered Brazilian minicar. It had the good old rear-mounted boxer.
